I don't think we are in a war of civilizations...yet. I don't doubt that the other side thinks and hopes that we are, and that our response to them, over the last few decades, has been mistaken on a number of fronts.
A real war of civilizations, as I have pointed out over and over again, only has one result. We'll be here, they won't.
I believe there is still time to avert that war, through a balance of force, diplomacy, self-sacrifice in a number of arenas, and careful consideration of our relationships with the Islamic and Arab world.
